LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 350,341, dated October S, 1886.

Application filed August 16, 1886.' Serial No. 211,045.

To all whom it may concern.-

Be it known that I, JOHN A. BERGAN, a citizen of the United States, residing at Holden, in the county of Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Loom-Shuttles, of which the following, together with the accompanying drawings, is a specification sufiiciently full, clear, and exact to enable persons skilled in the art to -which this invention appertains to make and use the same.

. The object of my present invention is to provide an efficient and serviceable catch mechanism, and to render the shuttle conven-. ient and desirable for manufacture and use. To this end my invention consists in ashuttle herein shown and described.

In the drawings, Figure l isa bottom view of the shuttle. Fig. 2 is a longitudinal central section. Fig. 3 is a longitudinal section of one end of the body. Fig. 4 is a transverse section at the position of line a' 'x in Fig. 2. Figs. 5 and 6 show the form of the latch, and Figs. 7 and 8 show the form of the spindlehead.

Referring to parts, B denotes the body or shuttleframe; C, the catch; D, the spindle, E, the fulcrum or pivot; F, the spring by means of which the spindleis held in positions of adjustment, andlthebobbin. Thespindle D is pivoted on the fulcrum-pin E, which passes through the spindle-head D, in the usual manner, and the spring F is seated in a recess formed in the body B, and is provided with a rounded bearing-piece, f, that fits into a semi-cylindrical cavity, f', in the spindlehead D', as shown, said spring being arranged to act in the manner ysubstantially as heretoforeemployed, for sustaining the spindle either at outward or inward position of adjustment.

wardly and backwardly projecting ear or tongue, d, and also with a transverse lug or the head at thepositions indicated. The catch C is made, as shown in Figs-.f5 and 6, with a transverse flange, c, to engage with the groove in the bobbin-head, a central longi- (No model.)

tudinal slot, c', with upwardly-projecting ears 5o c at either side thereof,.and with a rounded inwardly-curved rear end or tail, c, .This catch C is pivoted to the spindle-head Dby a pin, p, which passes laterally through the ears c2, and the projection or tongue d, which extends into the slot c between said ears, so K that the catch follows the action of thespindletongue d as the spindle is swung up and down. The body B is provided with a cavity for the reception of the spindle-head and catch C, VEo and backwardly-extending grooves b are formed in the sides thereof, into which the tail of the catch isintroduced and therein retained by the overhanging lips or flanges at m, the

tail of the catch being free to slide back-` and 63 A' forth longitudinally in the groove, but confined against swinging outward or inward. Vhen the end of the .spindle is raised from the interior of the shuttle-body, the catch is released from the groove in the bobbin-head by being slightly swung outward and'drawn forward by the tongue D of the spindle-head in a manner to avoid theliability of roughing or splitting up slivers from the bobbin-heada defect incident to many former'styles of 7; shuttle-catches, and a source of much waste and inconvenience. Vhen the 'spindle is down in place, the lug cl acts as a stop against the inner side of the catch,`which latter holds the bobbin securely in place. The action is indi- 8c cated by dotted lines in Fig. 2. The slot c in the catch affords convenient facility for oiling the fulcruni-pivots and spring-bearings With the construction shown the necessity of a spring for pressing in the catch is obviated, the spindle-adjustment spring F giving all the power necessary.

XVhat I claim as of my invention, and desire to secure by Letters Patent, is-

l. The combination of the shuttle-body pro- 9o vided with thegrooves b, the spindle having the tongue d on its head, and the slotted catch C, pivoted to said tongue at p, with its tail fitted to slide in the groove b and confined therein by overhanging lips, substantially as shown and described. 2. The combination of the body B, having the grooves Z, the spindle D, having the head D', fitted with the recess j, rearwardly and Tit-ness my hand this 5th day of August, ro downwardly projecting` tongue (l, and down- A.
